本研究は，動物の体のつくりやはたらきを知るための身近な生物の骨格標本を用いた学習方法の実践とその効果を報告するものである．

大阪市立東田辺学校の6年生児童40名（男子20名，女子20名）の協力を得て授業実践を行った．よく煮込むことのみによって作製した豚足の骨格標本および市販のニワトリの手羽元，さらに，イラスト付きスライドを参考資材として授業で用いた．骨を直に観察すること，骨の成長過を実感すること，造血器としての骨の役割，骨の中の細胞（骨をつくる細胞・骨をこわす細胞）の存在など，一般には視覚的に捉えることが困難な内容を，人と他の動物の標本やスライドを用いることで児童達に“見て”もらい，実感させた．また，観察のみならず骨の成長が全身にどのような影響をもたらすのかなど，より発展的な内容についても追加解説し，体のつくりと働きを捉えることを理解しやすい内容とした．

アンケートは授業前と授業後に行った．授業の前と後を比較すると，特に骨への知識や着眼点に著しい違いが見て取れた．さらに，骨病変や加齢性変化など，正常の骨の成長のみならず疾患までへも興味の幅を広げ，探究心・好奇心を涵養できた様子が窺えた．

結語として，身近な生き物を用いた実習形式の授業は，机上で得た知識を実感と納得に基づく“見識”へと知識の階層を昇華させ，新たな疑問を抱ける児童へと成長できるなど，教育効果が高い取り組みであることが示唆された．

 This paper considers how the partner exercise has been retained in physical education practice and school sports festival from elementary school to senior high school in japan after deleted from the course of study. The partner exercise was deleted from the course of study were 1953 in elementary school, 1958 in junior high school and 1960 in senior high school. The Ministry of Education by the official daily gazette from 1958, in addition, strengthened the restriction of the course of study. The most important part of this argument is that the reason why the partner exercise has been retained in the physical education practice and the school sports festival under strengthened the restriction of the course of study.
 The results of the considerations are summarized follows:
 In the course of study in elementary school (1949), the partner exercise belonged to the part of the calisthenics composed of three children without the pyramid building. Since the partner exercise deleted from the course of study in elementary school (1953), a lot of teachers through the discussion in physical education magazine recognized that the partner exercise is the same as the calisthenics. Therefore, the partner exercise has been exist in physical education practice in order to training physical fitness and mind.
 In the course of study in junior high school and senior high school (1951), the partner exercise belonged to the part of the “Kohgi” (= apparatus gymnastics, pyramid building, stunts and tumbling). Since the “Kohgi” deleted from the course of study in junior high school (1958) and senior high school (1960), the partner exercise recognized the calisthenics as like elementary school has been retained in physical education practice.
 A further important point is the relationship between the physical education practice and the school sports festival over the partner exercise. The partner exercise has been placed in the program of the school sports festival before practiced in physical education. Performing the partner exercise in the school sports festival needed a lot of time to prepare it, because many teachers and audience sought high performance for students. As a result, the partner exercise was practiced in physical education course in all year in order to complete it in the school sports festival.
 Finally, the main reason why the partner exercise has been exist in the whole school after deleted from the course of study was that a lot of teachers gave it highly educational philosophy which the character building through the school life.
